There is something about a 4" N frame. I bought a 24, 25, 27, 29, 57, 58, as well as a heavy duty and a 520. My 24 is one of the 80s gun and with a set of real stag grips is the gun I pack around most of the time. I even bought one of the new, factory engraved 29s. Just can't resist them. Shotgunner
